Did you know?Damn Dirty Ape
The Oozaru in the Budokai Tenkaichi series is variously used to represent either Gohan or Goku's youngest incarnations in the games' story modes. However, only Kid Goku is able to actively transform into it during gameplay.

In the movie-based game DragonBall Evolution, Oozaru represents Goku's true form. It is noticeably smaller than its Budokai Tenkaichi counterpart (although still large), and still wears Goku's clothing.
